IMPROVEMENTN BUTTONS.

TO ALL WGM IT MAY CONGERN Be it known that ,JoSnj1 n M. PRUG'GEILof thecity, county, and Stafte oi' New York, have invented o. new and improvedButton; and I- do hereby declare that the following is a. full, clear,und exact description pnnying drawings, forming part of this'specification.

Figures 1, 3, and 5 are side views of my improved b'utton. Figures and 4are bottom views of .the same. Similar letters of reference indicatecorresponding parte.'

thereof, which will eneble others skilled in the art to Ineke enduee theseme, reference being had-,to the accom- The object of this invention isto constructs, button, with its lfastening secured toit, in such amanner thrit Athe seid button may be easily applied to or detechedfremthe cloth at will, and may be firmly held thereon.,

vi'ith'ontinjuring the meteriei.

The invention consists in the use of spirally wound pointed wire, whichVis secured to the under side o'i" the buttoin'and which is screwed intothe cloth, when the button is to be fastened thereto. For better fittingthe button to the cloth, 'I also provide a. downward extension or besefor the button,l which base remains 'in the button-hole when thus used.l I

A isA theA button, which is provided with o base, a, between whic'hendthe body 'of the button u neck, maybe left,` as shown in fig. `l, orwhich may teperdownwords, as in'g. 5. To the beso al securely Afristen,either by soldering, pressing, or by any other suitable method, a metalwire, 0, which extends in a. etrziightline,4 4and at :i more orlessobtuse angle,ronly in proportion to the thickness of the cloth,and-is theh bent in a. spiral` line until it hns the requireddiometer.This snuie wire can 'be applied to buttons without a. bese; es. isshown.

more clearly in ig.- 3. i lt will be observed that the'spiral por/tienof the wire is 'perfectly horizontnl', not devi. ating from e perfectlevel7 and that-its end is pointed, so that it may easily be passedthrough the cloth.

Lam aware that spiral wires are already'used on buttons for the seinepurpose; but they are always wound similar to n cork-screw, the lowestshnrp point being -further from the lower surface of the button than anyother part of the wire. These wires project too for beyond', and cannotbe used practically, while my button cfm be easily applied and firmlyheldinl ny part of' the garments, whether the'materiuls be thick orthin,with? out any inconvenience to the wearer or detriment to the material.y

When the button istobe epplied,`fthe point of the wire c ie passed'throughthe cloth, and the button :is then turned until either the Wholewire has been passed through the cloth, or until appart off the windingshave 'penetrated the cloth, the cloth being, in the latter case, f ruilyheld' between the spiral windings ofthe wire.

The windings o' th'e wireinay 'oe varied at pleasure, and Ildo notwishto confine myself to any particular one of them. Y v

I om aware thatthc attachment of buttons'by means of. coils is notnewzndthat the coil has been seated in n hollow sbonk and collet.-v Thesedevices I do not claim'. But what I do claim, and desire to secure byLettere Patent, is l l i A button, having e. shank whose bese a isconcave, in the centre of .which is scoured, et an obtuse, angle, thewire coil c, whose convolution@ are in the same plane with the base,whereby the button is uniformlysupported'while holding theclothiclarnpod in the' concavity of the bese, substantielly asdescribed.A
